〜 Red Thread Instruction Manual 〜 ○ Characteristics of the Red Thread Visible only to angels, invisible to humans. Only angels can touch it and tie it to fingers. Humans have no sensation of touching it, nor do they feel it when it is tied to their fingers. It stretches infinitely, so it will never snap no matter how far apart the pair is.

○ Effects of the Red Thread The two people tied together will find each other attractive and naturally be drawn to one another. Note that since the effect only amplifies pre-existing goodwill, the thread will not make someone fall for a person they originally disliked. Even if they don't know where their partner is, they will feel an urge to head in that direction. The effect does not strengthen over time, but it is permanent as long as the thread remains tied.

○ How to Connect the Red Thread Tie one end of the thread to a man's pinky finger and the other end to a woman's pinky finger. However, only one thread can be tied to a single person's pinky.

○ How to Remove the Red Thread Once tied, there is no way to intentionally remove it, even for an angel. However, if both parties come to hate each other from the bottom of their hearts, the thread will vanish. This is a safety mechanism in case two incompatible people are tied together.

○ Precautions If tied to an angel's pinky, the effect applies to the angel as well. There is a past case where an angel fell in love with a human and intentionally tied the thread to themselves and the human, staying together for life. While there is no particular issue with humans and angels dating, the use of the Red Thread for such purposes is problematic. Ultimately, they were blessed by colleagues, had children, and lived happily, but since it was a clear abuse of authority, they initially received a severe warning. Needless to say, abuse of authority is strictly prohibited.
